To all whom it may concern:

Be it known that l, Hormon E. GRANT, a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania., have invented a new .and useful iquidtorage System, of which the 'following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure l is a sectional elevation of apparatus embodying' my invention; Fig. 2 is a side viewplfig. B is a vertical section of the measuring and valve portions of the apparatus; and Vig. 4L, is a detail sectional View of the valve. y

My invention has relation to a storage system for gasolene and other volatile liquids of that class wherein the liquid is forced out of a storage tank or reservoir by means of air pressure.

The object of the invention is to provide means of simple, novel and eilicient character whereby the quantity of gasolene deA li vered may be accurately measured as it is delivered.

`lelerring` to the accompanying drawings, in which I have illustrated the preferred embodiment of vmy invention, the numeral Q designates a closed storage tank of the desired capacity, which is preferably huried in the ground, as indicated, and which is provided with an upwardly extending fillingr neck This neck is preferably provided with a closingl cap 4, which can be 5 secured by a suitable lock 5.

G designates a supplemental tank below the bottoni of the main tank with a corninon separatingwall 7. This supplemental tank is of much smaller capacity than the main tank, and is provided in order that a liquid may be forced therefrom by the use of a smaller amount of air than would be possible when forced directly from the main tank. especially after the main tank became y partially emptied of its contents. Liquid is admitted from the main tank into the supplemental tank through a suitable valve casing or litting 8, having one or more lateral inlet openings 9, these openings being arranged to be closed by a suitable check valve when air is admitted to the supplemental tank. AThis check valve forms no ria-rt of the present invention. A. liquid outlet pipe 11 is connected to the upper end'of the fitting 8, and thence extends upwardly to alsuitable valve casing 12,l located above Spcification oi Letters Patent.

the ground at any convenient. point. A

short pipe section 13, open at both its upper valve in the fitting 8 is normally open so that liquid can flow 4freely from the main tank into the supplemental tank, but is closed, as above stated, when the air pressure is admitted to the supplemental tank.

14 is the pipe for admitting air to the supplemental tank and extends upwardly through the main tank and to the valve casing '12, above referred to. serves as the outlet'pipe for the gasolene and also leads to the valve casing 12.

In the valve casing 12 is a valve 15 of the turning plug type. This valve is seated in casing 12, and its stem is provided with a suitable actuating lever or handle 15al which is preferably arranged to be secure by a suitable lock, as indicated at 16. The

The pipe 11 alve has at one end portion a Cut-away 1 19 is a gasolene delivery pipe which isl arranged to be put in communication with the outlet pipe through the port 17.

2O is an air pum or other suitable source of'air ressure',.wh1ch is arranged to be connected y a pipe 21 through the port 18 with the air pipe 14. i

2Q is a vent pipe leading from the valve to another vent pipe 23, which is extended downwardly and communicates n.with the upper portion of the mainltank. l/Vith the valve in its normal closed positionas shown in Figs. -3 and 4, the vent pipe 22 is connected with the air pipe 14, through the port 18, thereby giving a normally open vent for the supplemental tank. The pipe 23 provides a. normally open vent for the main tank.

Q4 is measuring Vvessel of the desired capacity, which is connected in a pipe 25, which leads from' the valve 15 to 'the Vent pipe 23. Placed at each side of this Ineasuring vessel is an indicator 25a., each of' which has a passage therethrough in which is placed a vane or paddle 26, mounted'on a the pump 20 and supplemental tankfandv rocking shaft or axis 27, which has an eX-- tlieieonneetion between llie liquid outlet pipe ll and the liquid discharge pipe 19 is also closed. `Wlien it ie desired to obtain liquid from the supplemental tank, the valve is actuated so as to fully open the connnunication between the pipe ll and the pipe This movement ottlie valve also connects the air pump with tine pipe ll. Air pressure non' flows into the supplemental tunlt and forces liquid upwardly through the pipe l1, port 17 and 'the lower indicator 25a into the measuring reset-l llie movement oli the loner indicator' will .snow that liquid is properly flowing". As soon ae the measuring vessel becomes filled, the `liquid Vwill rise into tbe upper indicator 25a, and thus indicate that fact. If the air pump sliould be operated after the measuring tank is thus iilled, the excess liquid will simply flow into the pipe 23 and back into the inain tank. Villen the measuring vessel El has been filled, the vali/eis given a further movement to eennect the measuring tank With the delivery pipe l), and the liquid flows out of the measuring tank by gravity. "When the tank is emptied, the operation isrepeated. The lower indicator slions that the measuring tank llas been emptied. ln the normal position oil the valve, as shown in lig 3, the port l? communicates with the pipe ll to e suilioient extent to permit the rossel 2l to drain. Therefore, no liquid can normally remain in said vessel.

By the apparatus described, l provide e simple and etlicient system for the storage and deliifery of liquide, particularly gasolene and other `volatile liquids, und having means of simple and reliable character by which the exact amount ot the liquid delittered is autonnitieally measured.

. It will be understood that mi; invention is not limited in its application to the partiew 111er system which l, have herein eliown and described, since tbe measuring device which forms the main feature olI my invention is applicable to other systems, lt -will also be apparent that various changes .tney be made in. tlie details of the valve, in tbe connection noe-ene? of tbe measuring" device intotlie system, and
